Yosemite Nature Notes: Sky Islands

Most visitors to Yosemite National Park tour the Yosemite Valley and head out of the park. A small percentage of others take to the Tioga Road and destinations off of it. One area that the vast majority of visitors misses is along the roof of the park, where you'll find "sky islands." Fortunately, you can gain insights to these landscapes -- "high, flat plateaus ... found at elevations around 12,000 and 13,000 thousand feet" -- thanks to videographer Steven Bumgardner and his team at Yosemite.
